EDWIN B. STIMPSON, OF BROOKLYN, NEW YORK.

CARTRIDGE-BELT.

Laagste.

To all whom t may concern:

Be it known that l, EDWIN B. STIMPSON,

a citizen of the United States, residing in Brooklyn, county of Kings, and State of N ew York, have invented a certain new and useful Improvement in Cartridge-Belts, of l The object of the present invention is to provide an effective means for attaching two strips of sheet material of a like nature to each other at spaced apart points to form cartridge holding loops without detracting in any way from the tensile strength of the material.

`With this and other objects in view, the principal feature of the invention consists in forming the loops by attaching two strips of material, such as paper, to each other in a face to face relation at suitable intervals by means of glue or other tenacious adhesive material.

Another feature of the invention resides in the placing of suitable spacing members between the strips and in attaching the strips to opposite sides of the spacing members to form the cartridge holding loops.

A cartridge belt thus formed is simple and inexpensive in construction and possesses a sutliciently high degree of strength and durability to serve the purpose for which it is made. Obviously an enormous saving in the weight and volume of material employed is effected by the substitution of paper or other light and unsubstantial ma- 'terial for the comparatively thick webbing heretofore used in the art.

In the drawings,

Figure l is a face view, partly broken away, of a section of belt embodying the invention, and showing the manner in which adhesive material is applied to the layers to form cartridge holding loops.

rlhe cartridge belt shown in Fig. l comprises the two cartridge-engaging strips of material l and 2 which are secured to each other by the appiicationto one of the strips' of a coating of adhesive material 3 and then in pressing the remaining strip into Contact with the freshly prepared surface of the first strip. In order to form cartridge holding loops, the adhesive material is applied to the strips at spaced apartv points, as will lbe seen, and in areas extending across the entire width of the strip in the preferred embodiments of the invention. It will also be seen that the adhesive is so distributed1 that at one edge of the strip the coated portions occupy correspondingly wider areas, as at 4c, than along the opposite edge, in order to thereby provide loop portions of reduced size to accord with the reduced diameter 6 of the cartridge at the bullet-holding end thereof. The shoulders 5 formed by the gradual expansion of the coated strips 3 into the enlarged end portions 4 preferably shown in Fig. l the strip members l and 2 are formed of single thicknesses of material such as paper of a tough and tear-resisting nature that renders it well adapted to bear the strain incident upon its employment for this purpose. rlhe use of an adhesive instead of'employing metallic fasteners or stitching the parts together with thread, to form the cartridge holding loops 9, leaves the strips wholly unpanctured and unimpaired -in any way, so that their entire strength is available for securing a belt construction having the requisite tensile Vtake the same angular inclination as that of fthe shoulders 7 on the cartridges 8. In the preferred form of the invention I shown in Figs. 3 and 4C such a -are preferably securely held together strength. The adhesive material Yemployed referably not only possesses tenacious holding qualities, but also a considerable degree of fiexibility, so that it will withstand the manipulations to which the belts are subjected in operation.

Vhile the preferred embodiment ofthe invention is that shown in Fig. l, in which but two single thicknesses of material are made use of in forming a complete belt, I contemplate also the making use of comparatively thin and unsubstantial material such as a light grade of paper in which the requisite tensile strength issecured by the use of reinforcing cords, as in the inventions already referred to. In the embodiment construction is shown in which the main strip members 1 and 2 forming the belt are made up of thin strips folded over on themselves and including between the respective folds three reinforcing cords l() arranged one along each edge and Yone along the central portion of the belt in the manner indicated. The foldan the cords held in place therein by means of a suitable adhesive.

The adhesive coated portions 3 are arranged in much thesame manner that they are arranged in Fig. l, that is, they are expanded at 4 to form correspondingly restricted loop portions adapted to fit the reduced diameter of the bullet-holding end of thecartridge. In Figs. 5 and 6 there is shown a construction very similar to that shown in Figs. 3 and 4, except that four reinforcing cords 10 are made use of and distributed in pairs along the opposite lateral Vedges of the strips.

This provides a very eficient construction and one that will withstand the strain of vigorous use. While reference has been made to the use of paper as the preferred material, it is obvious that textile or other materials could also be einployed if desired, and that thin and comparatively unsubstantial materials could thusbe made use of in lieu of the heavy webbing heretofore employed. It is also obvious that the areas to which the adhesive is applied need not necessarily extend entirely across the strips, but that in certain circumstances adhesive applied adjacent to the opposite edges and leaving the central portion free would be suiiicient. While in the various modifications the belt -has been shown as made up of separate layers united by means of an adhesive, it is obvious that a single strip of material may be folded laterally vupon itself to form the belt, in which case openings might be provided for the cartridges along the folded. edge or the cartridges may be forced through the folded edge by utilizing the pointed bullets for the purpose.

In order to reduce to some extent the sharpness of the angle at which the loop portions of the belt are bent out of their position in contact with each other at the gummed portions 3, I contemplate the use of strip spacing members l2 such as is shown in Fig. 7 of the drawing. These spacing members are preferably given the same gen eral formation as the glued portions 3 of the strip 2 in Figxl and possess a substantial thickness for lthe purpose referred to. They Y are preferably attached to the strip at the bers and then in attaching the strips to the Vcorresponding sides thereof.

This forms a very efficient construction and a sectional view of the strips l and 2 with the interposed spacing member l2 is shown in Fig. 8 of the drawing.

Having thus described Iny invention, what I claim and desire to secure by Letters Patent of the United States is:

l. A cartridge belt comprising: layers of longitudinally reinforced paper placed in face to face relation, and spacing members inserted between said layers at intervals to form cartridge holding loops, said layers being attached to opposite sides of said spacing members.

2. A cartridge belt comprising: layers of longitudinally reinforced paper placed in face lto face relation, spacing members inserted between said layers at intervals to form cartridge holding loops, said layers being attached to opposite sides of said spacing members by means of an adhesive.

Signed at Brooklyn, in the county of Kings, and State of New York, this 21st day of May, 1918.
